I genuinely enjoyed my 1 month stay here, and would love to come back and stay even longer in the future. The wifi was incredibly fast and consistent throughout my stay, no issues at all. Don't be worried about being further away from the center of the city. The Bang Na BTS station is about a 3 minute walk from the complex and you'll be able to go anywhere within Bangkok reasonably fast. The host was great when it came to communication, she consistently replied to all my questions in a quick and timely manner. I highly recommend staying here.
